Abstract: 721,980. Self-baking electrodes. KAISER ALUMINUM & CHEMICAL CORPORATION. Sept. 12, 1952 [Sept. 13, 1951]. No. 22943/52. Class 39 (3). An electric furnace, e.g. for producing aluminium steel, or calcium carbide, has at least one self-baking electrode 11 comprising a horizontal, elongated, current-carrying, metallic core 12 surrounded by a layer of non-metallic, consumable electrode material, e.g, carbon paste 13, having an upper unbaked portion and a lower baked portion. The paste 13 is fed through a hopper 14, one side 15 of which is arcuately extended at 17 to form, with end plates 19, a mould for the paste 13 while it is being baked. Aluminium foil 22 prevents adhesion of paste 13 to the side 17 during clockwise rotation of the core 12 to introduce paste 13 into the bath 10 above which a plurality of parallel electrodes 11 are rotatably arranged. Rotation is transmitted to the cores 12 by a shaft 28 and worm gears 30 co-operating with gears 26 on extensions 24 of the cores 12, and electric current is led to the cores 12 from a connection 35 through a, conducting liquid 32, e.g. a molten metal, e.g. Hg, Zn, or Pb, in a container 33 in which dips a disc 31 mounted on each extension 24. The cores 12 may be hollow or solid, and may be. roughened on their outer surfaces. The electrodes 11 may be radially arranged about an annular bath 10, and they may, be vertically adjustable.

Abstract: 499,227. Tipping vehicles. BROMILOW & EDWARDS, Ltd., and SWIFT, H. W. Aug. 23, 1937, No. 23046. [Class 108 (i)] In hydraulic tipping gear for three-way-tipping vehicle bodies, including telescopic ram units pivotally mounted on trunnions 4 for movement in a lateral plane in a cradle 2 which itself is pivotally connected to the vehicle frame 3 by transversely-arranged trunnions 5, the liquid is conveyed from a pump or other device by a pipe 7 to a gland 8 on the outside of a hollow cradle-trunnion 5, through the trunnion, through a pipe 16 to glands or stuffing-boxes similar to the gland 8 on one set (not shown) of the ram-trunnions, then through annular or partannular ducts 17 in the ram cylinders 1 to the opposite ram-trunnions 4, and finally through junction-boxes 20 and piping 22 to the lower ends of the ram cylinders. As shown, each ram unit comprises an inverted cylinder 1 closed at its lower end and a telescopic ram slidable within the cylinder, the ram having at least two telescopic portions 31, 39, one (39) being adapted at its upper end for connection to the vehicle body. For end tipping the rams move in unison with the cradle pivoting about the trunnions 5 while for side tipping the cradle remains stationary and the outer ram moves a relatively greater distance than the inner ram, both rams pivoting about their respective trunnions 4. To tip the body liquid is pumped into the pipe 7 under the control of a manually-operated valve and passes through the trunnions 5, 4 down the pipe 22 which swings with the ram cylinder, and into the interior of the cylinder to force up the intermediate ram plunger 31, and simultaneously the liquid passes through a bore 37 in a spigot 34 on the ram plunger 31 to the interior of the plunger to force up the plunger 39. The plunger 39, which has a spherical bearing 44 and split retaining ring 47 for a ball 45 on a plate 46 secured to the vehicle body 40, is slidable in a guide collar 43 on the plunger 31 which in turn is slidable in a collar 42 in the cylinder 1. The pump may be driven from the vehicle engine or by an electric motor or may be hand operated.

Title: Improvements in or relating to the manufacture of epoxide resins
Inventor: LEWIS JOHN RICHARD
IPC: C08G59/00
Filed: 1954-08-10
Abstract: In the preparation of epoxide resins by reacting one mol dihydric phenol with from 1-2 mols. halogen-hydrin in the presence of alkali, the product is freed from alkali by solidifying the resin, reducing it to powder form, and then washing the powder with aqueous acid until free from alkali.  The washed product may be reacted with further dihydric phenol to obtain products of higher molecular weight and the phenol may be added to the powder prior to washing.  The viscosity of the resin condensate may be reduced to enable the grinding to be carried out easily by addition to the reaction mixture of an inert solvent, e.g. alcohol, glycol, dioxane.  In examples: (1) 228 parts 2,2-bis-(4-hydroxyphenyl) propane dissolved in 365 parts of a solution formed from 57 parts NaOH, 360 parts water and 190 parts alcohol; 102 parts epichlorhydrin are added and the temperature raised to 80-85 DEG  C. after which the remaining 242 parts NaOH are added; after refluxing and settling the hot resin is run into cold water, the solidified resin is ground whilst being neutralized with dilute acetic acid until a powder is obtained which passes through a 60 mesh sieve; (2) as in (1), the proportions of phenol and epichlorhydrin being 456/259 ; (3) the resin obtained in (2) is mixed with 70 parts of the phenol, and the mixture after neutralization and washing is fused at 150 DEG  C.

IPC: A61N5/06
Filed: 1955-08-12
Abstract: 813,118. Radiation therapy apparatus. QUARZLAMPEN G.m.b.H. Aug. 12, 1955, No. 23294/55. Class 81 (2). A therapeutic mercury discharge lamp has a filter which is substantially permeable to ultraviolet radiation of wavelengths in the range 315-400 mÁ and visible radiation but which absorbs ultra-violet radiation of shorter wavelengths, the filter being constructed or mounted to allow the passage of an adjustable amount of unfiltered radiation. A mercury lamp 1 is secured in sockets 4 along the axis of a reflector 2. A filter 3, which permits the passage of ultraviolet radiation of wavelength 366 mÁ but absorbs most of the ultra-violet radiation of shorter wavelengths, surrounds the lamp 1. The filter is axially displaceable by a nut 12 on the upper socket 4 to provide a gap between the lower socket 4 and the filter 3. In a modification, the lamp 1, Fig. 5, is perpendicular to the axis of reflector 2 and is surrounded by two telescopically arranged filters 27, 28. One of the filters 28 is adjustable axially to provide an adjustable gap between the filters 27, 28 for unfiltered radiation on the side adjacent the reflector 2. Alternatively (not shown) the lamp 1 arranged perpendicular to the axis of the reflector 2 is surrounded by a fixed filter having an opening on the side facing the reflector, the opening being adjustable by a movable shutter. In other constructions a lamp arranged along the axis of the reflector may be surrounded by a filter comprising strips parallel to the reflector axis and pivotal to provide gaps through which unfiltered radiation passes. Pivotal louvre-like filter strips 16, Fig. 4, may be arranged across the mouth of the reflector 2 in front of the lamp 1.

Title: Improvements in or relating to the extraction of the medicinally active component oflithospermum erythrorhizon
Inventor: OTSUKI KINZO
IPC: A61K36/00
Filed: 1954-08-13
Abstract: The medicinally active component of Lithospermum erythrorhizon is obtained by extracting under substantially acidic conditions with a chlorohydrocarbon which is nearly or completely incombustible and heavier than water, covering the solvent with an aqueous layer, making the aqueous layer alkaline by addition of alkali hydroxide to transfer the medicinally active component to the aqueous layer and separating the layers.  Carbontetrachloride, chloroform or trichloroethylene may be used-in the commercial forms both carbontetrachloride and chloroform are slightly acid and further acid need not be added.  The organic solvent layer after separation may be acidified e.g. with hydrochloric, sulphuric or phosphoric acid, and further extracted.  The active component may be precipitated from the aqueous layer by addition of acid (HCl) and separated by centrifuging or filtration.  Any active material remaining in the aqueous layer may be extracted with ether: if desired the precipitate may be dissolved in the ethereal extract and the solution evaporated to give a homogeneous product.

The apparatus is also provided with a drying zone at the thread collection end of at least the lower roller, the longitudinal grooves being made helical for a short distance as the drying zone is approached, the helical portions of the grooves being right-handed for clockwise rotation of the roller (as viewed from the feed end of the latter) and vice versa.  The grooves may be normal to the surface of the roller, as shown at 5 in Fig. 3, or at a backward or, preferably, a forward angle, as shown at 6 and 7 in Figs. 4 and 5 respectively.  As shown in Fig. 8, the thread is led from the acid bath to the initial end 15 of the lower roller 3 of a pair of mutually inclined rollers and progresses in helical loops to the drying zone 18.  The longitudinal grooves 14 disperse air bubbles forming at the points where the loops of thread leave the bottom roller and thus prevent adjacent loops from becoming entangled with one another even when they are closely spaced.  Wash water is applied to the thread during its path of travel from the end 15 of the roller to the beginning of the drying zone 18 and is propelled by the helical portion 16, 17 of each groove 14 towards the portion 21 of the roller containing the further longitudinal groove 17, 19, where it is drawn off, being prevented from entering the drying zone 18 by the helical groove 19, 20.  No grooves are needed in the drying zone. The Provisional Specification describes also rollers provided with longitudinal ridges, as shown at 4 in Fig. 6, and rollers in which the grooves are in relatively short lengths, as shown at 8 to 12 in Fig. 7.  In the latter case the grooves are staggered so that the ends overlap and any transverse section 13 of the roller cuts through the desired number of grooves (in this case four).
